1/34
POWER CABLE TEST VAN HVT-35
The power cable test van performs the following
functions:
1. DC high voltage up to 40 kV for withstand testing
of power cables
2. Burning down defective insulation of power cables
3. Pre-locating high voltage cable faults by theimpulse reflection method (TDR), the arc reflection
method, the arc reflection plus method, the voltagedecay method and the impulse current method
4. Locating cable faults by the acoustic method andinductive method
5. Audio frequency cable route tracing and cable
depth evaluation
A. POWER CABLE TEST/FAULT LOCATION
1 CABLE FAULT LOCATION AND HIGH VOLTAGE TEST
The CFL40A cable fault location system has been developed to provide quick, effective,
accurate and safe fault location, reducing system outages and customer minutes lost. The
system comes as two separate modules, making it suitable for mounting in a vehicle. The HVmodule contains all of the High Voltage elements. Control of all of the HV elements and CFL
methods is by a separate control panel, which also houses the large screen colour TDR.
HV Testing (proof testing)
The system proves the integrity, identifies and confirms fault conditions in cable networks. It
can be used for sheath testing at 5 or 10 kV. The selectable over-current trip levels provide
protection, and leakage current is shown on the analogue metering.
Fault Pre-location
After identifying the type of fault, low or high voltage methods of pre-locations are used to

determine the fault position. TDR pre-locate cable faults using pulse echo, arc reflection,
impulse current (ICE) or the voltage decay method. In pulse echo mode, a real time trace and a
stored trace are viewed simultaneously on the large colour display, allowing comparison and
difference measurements to be made.
The MTDR1 features auto-ranging, auto distance to fault and operator assist functions that
guide the operator through the fault locating process. In the Arc Reflection mode, faults are
stabilised by creating a temporary bridge to earth. During this condition, a standard pulse
echo measurement is taken into what is effectively a short circuit fault. Arc Reflection plus,
lets you view and analyse up to 14 traces, taken during the period of the arc. ICE and Voltage
Decay methods are both transient analysis methods of pre-location which uses either a linear
coupler or voltage divider.
Fault Conditioning
Fault conditioning is used to stabilise unstable, flashing or high resistance faults. The Fault
Locator system incorporates both Proof/Burn and ARC Reflection modes. Proof/Burn using
the high voltage output and following a breakdown of the cable under test, a high current is
applied, creating a carbon bridge, stabilising the fault condition. This allows pre-location and
pinpoint location of unstable faults. ARC Reflection, not widely recognised as a fault
condition method, the Arc Reflection method stabilises faults by creating a temporary
bridge to earth, enabling standard pulse echo techniques of pre-location to be used.

4/34
ergonomically designed, rugged case that is IP54 rated. The unit can be easily carried hands
free using the adjustable neck strap. The MPP2000 is used to detect the acoustic and
electromagnetic fields. Both fields are generated by the flashover at the point of fault, which
has been generated by the HV impulse caused by a surge generator. Detection is via a
lightweight ground microphone, which has a physical shield to reduce external wind noise.
For easy interpretation, the receivers display shows clear, unambiguous readings. The user
interface features standard directional and select arrow keys for easy navigation.
For operator comfort, and for use when the operator is wearing a safety helmet, the MPP2000
is supplied with behind-the-head headphones. Active noise-cancelling headphones are
available as an optional accessory. Additionally the unit has a built-in auto mute,
eliminating all ambient noise, which is activated when the ground microphone is raised from
the ground. The unit has an integral loudspeaker, the volume of which can be adjusted for
user comfort via the touchpad controls. A single pushbutton mutes the output both on the
headphones and loudspeaker simultaneously.

The MPP2000 provides:
Detection of the acoustic discharge (thump) andmeasurement of acoustic signal strength.
Detection and indication of the electromagnetic signalstrength.
Measurement of time delay between acoustic andelectromagnetic signals.
Indication of the direction to fault.
Calculated relative distance to fault.
APPLICATIONSThe MPP2000 pinpoints faults in underground powercables using acoustic, electromagnetic and time delaymethods, enabling quick and accurate pinpoint location ofunderground cable faults.
The location of the buried cable is indicated by theintensity of the electromagnetic field produced by the HVpulses of a surge generator. The bargraph indicator of theMPP2000 shows a maximum intensity of the magnetic fielddirectly above the cable, reducing as the operator movesaway from the route of the cable.
Accurate and fast fault locating is accomplished using the
coincidence measurement of the acoustic signal, in timerelation to the electromagnetic signal produced at theflashover or point of fault.
The receivers display shows the acoustic signal strengthand the time delay between the electromagnetic surge andacoustic event.
When directly over the fault, the time difference is at aminimum and the acoustic level is at a maximum. This isespecially useful when the cable is in a duct or pipe wherethe acoustic signal could mislead the operator.

L1070 and L1071Portable Locator
DESCRIPTIONUnparalleled in capability, the L1070 and L1071 PortableLocators locate buried cable and pipe in varioussituations. Capable of locating long or short ranges,inductive or conductive, active or passive, the units deliverquick and accurate results with a user-friendly interface.Whereas the L1070 uses a disposable battery type, the
L1071 requires a rechargeable one.
Operating the receiver at multiple frequencies optimizesperformance for the specific needs of the user. Lowfrequency of 815 Hz provides longer range and reducederrors from adjacent cables, ideal for electric powerservices. High 82 kHz frequency will path locate past badtelephone bonds, locate underground stubs and permitinductive locating with either the optional flexible coupleror direct soil induction. A special design feature on bothunits allow the user to select and compare receiverinformation on two frequencies simultaneously, withouthaving to return to the transmitter. Excellent passive 50/60Hz locating will pinpoint active power lines and other
utilities where AC is present without the use of thetransmitter.
The portable locator also features SONDE detection andlocating. By selecting this feature, the user is able tochoose a SONDE that will match the same frequency andthe receiver.
APPLICATIONSFlexibility remains the key strength of reaching difficult,multi-point, grounded utility locating applications.Combining high power at low frequency virtuallyeliminates the false coupling into adjacent objects andallows the high transmitter power to burn a signal past
several grounds and into multiple distributed grounds.Multi-grounded electrical distribution service, continuouslygrounded water pipes, multi-grounded telephone shieldwiring, highly capacitive, cathodically protected coated gaspipes and CATV systems all benefit from the flexibility ofthe L1070 and L1071.
Conductor current readout on the units give the userinformation on the amount of current flowing on the targetconductor with correction for changes in depth. To tracethe direction where the transmitter signal is divided orwhere it goes into the soil at an insulation ground fault,press the CURRENT button. This feature is useful incathodically protected systems with ground faults.
An optional ground return probe allows ground faultdetection on unshielded electric services or sheath faultson telephone services through the technique of voltagegradient.
FEATURES AND BENEFITS
Multiple transmit/receive frequencies provide accuratelong or short range locates.
Push-button depth measurements up to 15 ft (4.6 m)quickly identify service depths prior to digging.
Passive 60 Hz detection serves as an excellent safetyfeature for identifying live underground primary andsecondary utility cables.
AC circuits in common trench situations. Passivedetection also allows convenient locating of energizedelectric services.
High power at low frequency solves the difficult multi-point grounded utility locating problem.

CFL40A2000Vehicle Mountable Cable Fault Locationand High Voltage Test Solution
CFL40A SERIESVehicle Mountable Cable Fault Location and High Voltage Test Solution
Fault Pre-locationAfter identifying the type of fault, low or high voltagemethods of pre-locations are used to determine the faultposition.
TDRpre-locate cable faults using pulse echo, arcreflection, impulse current (ICE) and the optional voltagedecay method. In pulse echo mode, a real time traceand a stored trace are viewed simultaneously on the
large color display, allowing comparison and differencemeasurements to be made.
MTDR100features auto-ranging, auto distance to faultand operator assist functions that guide the operatorthrough the fault locating process.
In theArc Reflectionmode, faults are stabilized bycreating a temporary bridge to earth. During thiscondition, a standard pulse echo measurement is takeninto what is basically a short circuit fault.
Arc Reflection plusprovides the operator with the addedadvantage of having the ability to view and analyze upto 1024 traces (range dependent) taken during the periodof the arc.
During Differential arc reflectionmode unwanted andconfusing reflection is removed leaving a clean tracewith only the fault position, point being displayed bya positive pulse. This method is especially suited inlocating high-resistance faults in complex cable systems.
ICEandVoltage Decaymethods are both transientanalysis methods of pre-location which utilize either alinear coupler or voltage divider.
Fault Conditioning
Fault conditioning is used to stabilize unstable, flashingor high resistance faults. The Megger fault locator systemincorporates both proof/burn and arc reflection modes.

Proof/Burn Using the high voltage output and following a
breakdown of the cable under test, a high current isapplied, creating a carbon bridge, stabilizing the faultcondition. This allows prelocation and pinpoint locationof unstable faults.
Arc ReflectionNot widely recognized as a fault condition method, ahigh current is applied to the cable under test, creatinga carbon bridge and stabilizing the fault condition. Thisallows pre-location and pinpoint location of unstablefaults.
Acoustic pinpoint fault location
Accurate pinpoint fault location is achieved using theacoustic method, whereby the powerful surge generator(thumper) and a receiver (MPP2000) are used. The Meggeracoustic and electromagnetic pinpointer shows directionand distance to fault.

MPP2000Megger Pinpointer
DESCRIPTIONThe Megger Pinpointer model MPP2000 is specificallydesigned to accurately and quickly pinpoint faults inunderground cable networks. Easy-to-access menus provideadvanced users the flexibility and features they desire.
The MPP2000 is housed in a lightweight, ergonomicallydesigned, rugged case that is IP54 rated. The unit canbe easily carried hands free using the adjustable neck
strap. In addition, the instrument can be used with anymanufacturers surge generator (thumper).
The MPP2000 is used to detect the acoustic andelectromagnetic fields. Both fields are generated by theflashover at the point of fault, which has been generated bythe HV impulse caused by a surge generator. Detection isvia a lightweight ground microphone, which has a physicalshield to reduce external wind noise.
For easy interpretation, the receivers display shows clear,unambiguous readings. The user interface features standarddirectional and select arrow keys for easy navigation.
For operator comfort, and for use when the operator is
wearing a safety helmet, the MPP2000 is supplied withbehind-the-head headphones. Active noise-cancellingheadphones are available as an optional accessory.Additionally the unit has a built-in auto mute, eliminatingall ambient noise, which is activated when the groundmicrophone is raised from the ground.
The unit has an integral loudspeaker, the volume of whichcan be adjusted for user comfort via the touchpad controls.A single pushbutton mutes the output both on theheadphones and loudspeaker simultaneously.
The MPP2000 provides:
Detection of the acoustic discharge (thump) andmeasurement of acoustic signal strength.
Detection and indication of the electromagnetic signalstrength.
Measurement of time delay between acoustic andelectromagnetic signals.
Indication of the direction to fault.
Calculated relative distance to fault.
APPLICATIONSThe MPP2000 pinpoints faults in underground powercables using acoustic, electromagnetic and time delaymethods, enabling quick and accurate pinpoint location ofunderground cable faults.
The location of the buried cable is indicated by theintensity of the electromagnetic field produced by the HVpulses of a surge generator. The bargraph indicator of theMPP2000 shows a maximum intensity of the magnetic fielddirectly above the cable, reducing as the operator movesaway from the route of the cable.
Accurate and fast fault locating is accomplished using the
coincidence measurement of the acoustic signal, in timerelation to the electromagnetic signal produced at theflashover or point of fault.
The receivers display shows the acoustic signal strengthand the time delay between the electromagnetic surge andacoustic event.
When directly over the fault, the time difference is at aminimum and the acoustic level is at a maximum. This isespecially useful when the cable is in a duct or pipe wherethe acoustic signal could mislead the operator.

L1070 and L1071Portable Locator
DESCRIPTIONUnparalleled in capability, the L1070 and L1071 PortableLocators locate buried cable and pipe in varioussituations. Capable of locating long or short ranges,inductive or conductive, active or passive, the units deliverquick and accurate results with a user-friendly interface.Whereas the L1070 uses a disposable battery type, the
L1071 requires a rechargeable one.
Operating the receiver at multiple frequencies optimizesperformance for the specific needs of the user. Lowfrequency of 815 Hz provides longer range and reducederrors from adjacent cables, ideal for electric powerservices. High 82 kHz frequency will path locate past badtelephone bonds, locate underground stubs and permitinductive locating with either the optional flexible coupleror direct soil induction. A special design feature on bothunits allow the user to select and compare receiverinformation on two frequencies simultaneously, withouthaving to return to the transmitter. Excellent passive 50/60Hz locating will pinpoint active power lines and other
utilities where AC is present without the use of thetransmitter.
The portable locator also features SONDE detection andlocating. By selecting this feature, the user is able tochoose a SONDE that will match the same frequency andthe receiver.
APPLICATIONSFlexibility remains the key strength of reaching difficult,multi-point, grounded utility locating applications.Combining high power at low frequency virtuallyeliminates the false coupling into adjacent objects andallows the high transmitter power to burn a signal past
several grounds and into multiple distributed grounds.Multi-grounded electrical distribution service, continuouslygrounded water pipes, multi-grounded telephone shieldwiring, highly capacitive, cathodically protected coated gaspipes and CATV systems all benefit from the flexibility ofthe L1070 and L1071.
Conductor current readout on the units give the userinformation on the amount of current flowing on the targetconductor with correction for changes in depth. To tracethe direction where the transmitter signal is divided orwhere it goes into the soil at an insulation ground fault,press the CURRENT button. This feature is useful incathodically protected systems with ground faults.
An optional ground return probe allows ground faultdetection on unshielded electric services or sheath faultson telephone services through the technique of voltagegradient.
FEATURES AND BENEFITS
Multiple transmit/receive frequencies provide accuratelong or short range locates.
Push-button depth measurements up to 15 ft (4.6 m)quickly identify service depths prior to digging.
Passive 60 Hz detection serves as an excellent safetyfeature for identifying live underground primary andsecondary utility cables.
AC circuits in common trench situations. Passivedetection also allows convenient locating of energizedelectric services.
High power at low frequency solves the difficult multi-point grounded utility locating problem.
